LPC11E6x
32-bit ARM Cortex-M0+ microcontroller
TRST/PIO0_14 33 46 69
[3]
I; PU IO TRST — Test Reset for JTAG interface. In boundary scan
mode only.
IO PIO0_14 — General-purpose digital input/output pin.
AI ADC_6 — A/D converter, input channel 6.
O CT32B1_MAT1 — Match output 1 for 32-bit timer 1.
O U1_TXD — Transmitter output for USART1.
SWDIO/PIO0_15 37 50 81
[3]
I; PU IO SWDIO — Serial Wire Debug I/O. SWDIO is enabled by
default on this pin. In boundary scan mode: TMS (Test
Mode Select).
IO PIO0_15 — General-purpose digital input/output pin.
AI ADC_3 — A/D converter, input channel 3.
O CT32B1_MAT2 — Match output 2 for 32-bit timer 1.
PIO0_16/WAKEUP 38 51 82
[4]
I; PU IO PIO0_16 — General-purpose digital input/output pin. This
pin also serves as the Deep power-down mode wake-up
pin with 20 ns glitch filter. Pull this pin HIGH externally
before entering Deep power-down mode. Pull this pin LOW
to exit Deep power-down mode. A LOW-going pulse as
short as 50 ns wakes up the part.
I ADC_2 — A/D converter, input channel 2.
O CT32B1_MAT3 — Match output 3 for 32-bit timer 1.
- R_8 — Reserved.
PIO0_17 42 56 90
[6]
I; PU IO PIO0_17 — General-purpose digital input/output pin.
O U0_RTS
— Request To Send output for USART0.
I CT32B0_CAP0 — Capture input 0 for 32-bit timer 0.
IO U0_SCLK — Serial clock input/output for USART0 in
synchronous mode.
PIO0_18 45 60 94
[6]
I; PU IO PIO0_18 — General-purpose digital input/output pin.
I U0_RXD — Receiver input for USART0. Used in UART
ISP mode.
O CT32B0_MAT0 — Match output 0 for 32-bit timer 0.
PIO0_19 46 61 95
[6]
I; PU IO PIO0_19 — General-purpose digital input/output pin.
O U0_TXD — Transmitter output for USART0. Used in UART
ISP mode.
O CT32B0_MAT1 — Match output 1 for 32-bit timer 0.
PIO0_20 10 12 17
[6]
I; PU IO PIO0_20 — General-purpose digital input/output pin.
I CT16B1_CAP0 — Capture input 0 for 16-bit timer 1.
I U2_RXD — Receiver input for USART2.
PIO0_21 17 22 33
[6]
I; PU IO PIO0_21 — General-purpose digital input/output pin.
O CT16B1_MAT0 — Match output 0 for 16-bit timer 1.
IO SSP1_MOSI — Master Out Slave In for SSP1.
